Re: [Exim] Getting around my isp when they block port 25

I think there are three obstacles in doing that:
1. not every DHCP server publicize mx server, and exim [as well every
other MTA/MUA] does not recognize
them, so if you are on the move you have to change it every time
2. If you use authentication (for example here you can send to internal
distribution list only if you authenticate ...)
3. Yaou lose the control on delivery (for example here if someone send a
message can ask the net admin to check if it has been delivered, or if not
where is the problem)
